Question by: Jerry W on Feb 2, 2026, 12:33 PM
Been running Permco gear pumps on our trucks for years and this 2-1/2 unit keeps coming up when I search for replacements. That C1DD41 number match up with this one?
Answer by: Customer Support on Feb 4, 2026, 6:28 AM
Yeah, C1DD41 is listed as an alternate part number for this unit, so if that's what your current pump is tagged with, you're looking at the right one. The supplier part number is LZ-0577-17, which is how it's catalogued here, but both references point to the same pump.
